Many multifamily houses are produced by small or medium size enterprises (SME's). These developers produce a substantial number of residential units per year. They have normally limited resources and need to have easy access to cost - effective structural solutions. Typical buildings comprise two storeys and four to eight flats. Due to costs and production efficiency these buildings are produced in light material, mainly wood. Each building is unique and the limited size of each project means that it cannot defray costs to adapt each building of interest, to available building system on the market. Instead, the builders need to have access to; 1. structural design guidelines to secure dimensions and acoustic performance; 2. assembly information regarding details; 3. process guidance to minimize risk exposure, secure the final result. This paper describes a typical design procedure and final results, for a small two - storey building comprising six residential units. The procedure fits to an SME, with limited resources for technical development. The building was designed and erected presupposing that everything has to be built "on site". This paper is also an introduction to a new guidance book, being prepared within the Swedish research project AkuLite.
